Explaining insurance-related and racial disparities in the surgical management of patients with acute appendicitis

BackgroundRace and insurance status influence the likelihood of undergoing laparoscopic appendectomy (LA) versus open appendectomy for the treatment of acute appendicitis. We hypothesized that these disparities are caused by presenting hospitals’ use of LA.MethodsThe analysis included 26,104 appendectomies for acute appendicitis in New York State during 2003 and 2004. Multiple logistic regression was used to determine independent predictors for undergoing LA versus open appendectomy.ResultsBefore adjustment for individual hospital use of LA, both white patients (odds ratio [OR] = 1.28, 95% confidence interval [CI] 1.21–1.36; P < .0001] and privately insured patients (OR = 1.52, 95% CI 1.44–1.61; P < .0001) were more likely to undergo LA. Controlling for differential hospitals’ use of LA decreased the OR for laparoscopic surgery to 1.08 (95% CI 1.01–1.15; P = .04) for white patients and to 1.22 (95% CI 1.15–1.31; P < .0001) for privately insured patients.ConclusionsDifferences in presenting hospitals’ use of LA maintain racial and, to a lesser extent, insurance-related disparities in the surgical management of patients with acute appendicitis.
